One may wonder where the enzyme components in supplements come from. Well, there are actually three main sources of enzymes: plant, animal, and microbial derivatives.

Most enzymes are hydrolytic, meaning they react with water. Plant species are naturally derived from plants. For example papain from papaya latex and bromelain from pineapple juice.

Animal enzymes come from the pancreas, liver, or stomach of animals such as pigs, cattle, and cattle. they are similar to those found in humans and are therefore prescribed by doctors to patients with pancreatitis or pancreatic cancer. An example of such a recipe is pancreatin, which comes from the pancreas of pigs.

Microbial enzymes are derived from microorganisms and are produced by the fermentation of these organisms. Microbes include fungal and bacterial amylase, diastase, and others. Most of these dietary supplements are made from plant and microbial substances. 

This is mainly because these sources have a wider range of pH, temperature, and substrate specificity. Not only can they act in the mammalian digestive system, but they are most stable throughout the digestive tract. This means they are safe and can be distributed without a prescription.

Animal enzymes, on the other hand, must be coated with an enteric coating so that they can reach the stomach without losing strength. Also, they have a lower pH range, similar to amylase.
